# Battery Curve
|
|
|
|
## 1. Function Overview
|
|
|
|
The Battery Curve module belongs to the Basic Traceability module of the MES system's Data Middle Platform. It is used to query the charge/discharge curve data of batteries in each process, displaying the changing trends of voltage, current, and capacity over time in visual charts. This helps process and quality personnel analyze battery performance.
|
|
|
|
**Core Functions:**
|
|
|
|
- Battery Process Query: Query all process records of a battery by battery ID
|
|
- Curve Chart Display: Display voltage, current, and capacity curves using multi-axis line/bar charts
|
|
- Chart Interaction: Support zoom, save chart as image, and other interactive functions
|
|
- Tray Curve View: Support jumping to external curve viewer to view curve data of all batteries in a tray
|
|
- Data Export: Support exporting all curve data files of the current process as a ZIP package
|
|

## 4. Curve Chart Display
|
|
|
|
### 4.1 Chart Description
|
|
|
|
After clicking on a process record on the left, the right panel displays the charge/discharge curve chart for that process. Basic information of the record is shown at the top of the chart.
|
|
|
|
**Basic Information:**
|
|
|
|
| Field | Description |
|
|
|-------|-------------|
|
|
| Equipment ID | Equipment ID that executed this process |
|
|
| Battery Sequence | Battery sequence number in the equipment channel |
|
|
|
|
### 4.2 Curve Data Description
|
|
|
|
The chart displays three data curves simultaneously, each with its own Y-axis scale:
|
|
|
|
| Curve | Display Type | Y-axis Unit | Description |
|
|
